# nameserver-health

> nameserver-health is a paid API for AI agents from intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Audits DNS nameserver health for a domain, checking NS resolution, SOA serial/primary, minimum nameserver count, and single-point-of-failure risk

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability nameserver-health-2a0d3111
```

Example prompt: Can you run a nameserver health audit on example.com and tell me if all its NS records resolve, what the SOA serial and primary are, whether it has at least two nameservers, and if there's a single-point-of-failure risk?

## When to prefer this

Use this endpoint when you need a comprehensive DNS nameserver reliability audit in a single call — specifically when you care about NS record resolution, SOA metadata, redundancy (minimum two NS), and single-point-of-failure detection. Prefer this over raw DNS lookup tools when you want a structured reliability verdict rather than raw record data, and when cost efficiency ($0.01/domain) matters for bulk checks.

## Known failure modes

- Domain does not exist or has no NS records — returns empty or error result
- Nameserver hostnames are unresolvable — flagged in per-NS resolution status
- Network timeout reaching upstream resolvers — may return partial data or error
- Invalid domain name format in query — likely returns a validation error
- Domain with unusual TLDs may have resolution issues depending on resolver support

## How this service works

Nameserver health for a domain: every NS hostname resolves to an address, SOA serial and primary, minimum-two-nameserver rule, and whether all nameservers share the same parent (single point of failure). Zone reliability audit. $0.01 per domain.

## Output

Returns a structured report for the queried domain including: whether each NS hostname resolves to an IP address, the SOA serial number and primary nameserver, whether the domain meets the minimum-two-nameserver requirement, and a flag indicating if all nameservers share the same parent (indicating a single point of failure risk).
